weather forecasting
Educated guesses (Statistical data, probability, etc). There is no known method for predicting (forecasting) when an earthquake might strike. Seismographs are used to detect but cannot predict earthquakes.
Perictance Method
The Strength and Frequency Method only predicts how often an earthquake of a particular magnitude will occur. The Gap Hypothesis only predicts where another earthquake is most likely to occur along a fault line. Neither method will predict where the next earthquake will occur in the world, or predict an earthquake happening in a random spot, or predict both the location and strength of an earthquake.
